(Cimicifuga racemosa)
Black cohosh is a tall perennial plant that grows in eastern and central areas of the United States. Black cohosh was used by Native Americans as a traditional folk remedy for womens' health conditions, such as menstrual cramps and hot flashes, arthritis, muscle pain, sore throat, cough and indigestion. The juice of the plant was used as an insect repellent and was made into a salve and applied to snake bites.
The parts of the plant used medicinally are the fresh or dried roots and rhizomes (underground stems). The active compound is believed to be 26-deoxyactein.
How black cohosh works isn't understood. It was once thought to have estrogen-like activity, but there is growing evidence that it does not.
Black cohosh is one of the more popular herbal remedies for menopausal symptoms, such as hot flashes, night sweats, migraines, mood disturbances, heart palpitations and vaginal dryness. Initial research on black cohosh suggests that it may improve some menopausal symptoms for up to six months. In fact, in 2001, the American College of Obstetricians and Gynecologists stated that black cohosh may be helpful in the short-term (less than 6 months) for menopausal hot flashes.
A recent, year-long study on black cohosh, however, didn't find that it had any significant benefit in women with hot flashes or night sweats. Researchers from the National Institute on Aging and the National Center for Complementary and Alternative Medicine gave 351 peri-menopausal and post-menopausal women either black cohosh, black cohosh combined with other herbs, the black cohosh/herb blend plus a soy-enhanced diet, hormone replacement therapy or a placebo.
